Chevy Trailblazer P0128: Coolant Thermostat – Below Temp
P0128 is a relatively common OBDII trouble code. It is triggered when your Chevy Trailblazer‘s coolant temperature fails to reach the proper operating temperature.
It’s a generic powertrain code, which means that regardless of who manufactured the vehicle, it’ll have the same meaning (1996+).
